This is the third and final section of a paper, "Oxford Realism", co-written with Charles Travis. -/- A concern for realism motivates a fundamental strand of Oxford reflection on perception. Begin with the realist conception of knowledge. The question then will be: What must perception be like if we can know something about an object without the mind by seeing it? What must perception be if it can, on occasion, afford us with proof concerning a subject (...) matter independent of the mind? (shrink)

The German Johannes Sharpe is the most important and original author of the so called "Oxford Realists": his semantic and metaphysical theories are the end product of the two main medieval philosophical traditions, realism and nominalism, for he contributed to the new form of realism inaugurated by Wyclif, but was receptive to many nominalist criticisms. Starting from the main thesis of Wyclif's metaphysics, that the universal and individual are really identical but formally distinct, Oxford Realists introduced (...) a new type of predication, based on a partial identity between the entities for which the subject and predicate stood, called predication by essence, and then redefined the traditional post-Aristotelian categories of essential and accidental predication in terms of this partial identity. Sharpe substantially shares the metaphysical view and principles of the other Oxford Realists, but he elaborates a completely different semantics, since he accepts the nominalist principle of the autonomy of thought in relation to the world, and Ockham's explanation for the universality of concepts. Unfortunately, this semantic approach partially undermines his defence of realism, since it deprives Sharpe of any compelling semantic and epistemological reasons to posit universalia in re. Therefore, Sharpe's main ontological theses certainly are sensible and reasonable, but, paradoxically, within his philosophical system they cannot in any way be considered as absolutely consistent.

The subject of this book is an epistemological consideration concerning the nature of knowledge. But other than the most essays on the subject of knowledge, here I am going to deal with a largely overlooked account to try to find an answer to the question of knowledge. This is the mental state account of knowledge. Or to put it into the main question: is knowledge a mental state? Now, the question is: Why is the epistemic thinking of Cook Wilson, Prichard (...) and Austin afflicted with such ignorance in contemporary epistemic discussions? The answer is: an unreflected Platonian heritage during 2000 years of epistemic thinking - a notion which is similar to a point Hetherington has called "epistemic absolutism". So my main conclusion here is: the JTB thesis (knowledge is some aspect of justified true belief) is insufficient in order to give an account of the nature of knowledge. A consequence from this is: all the epistemic theories which are dealing with the JTB thesis are based on deficient assumptions. Hence their results - notably the well-known externalism/internalism debate - are insufficient, too. So, there is a need for a new theory of knowledge based on the MS thesis. (shrink)

Is there more to the recent surge in political realism than just a debate on how best to continue doing what political theorists are already doing? I use two recent books, by Michael Freeden and Matt Sleat, as a testing ground for realism’s claims about its import on the discipline. I argue that both book take realism beyond the Methodenstreit, though each in a different direction: Freeden’s takes us in the realm of meta-metatheory, Sleat’s is a genuine (...) exercise in grounding liberal normative theory in a non-moralistic way. I conclude with wider methodological observations. I argue that unlike communitarianism (the previous contender for the discipline’s renewal), realism has the potential to open new vistas, though their novelty is to a large extent relative to the last forty years or so: realism is best thought of as a return to a more traditional way of doing political philosophy.

Morality seems to play a special role in human life distinct from conventional norms, like those of etiquette, or simple preferences based on subjective tastes. There are various theories of the foundations of morality, some of which treat morality as 'subjective' in an important way. 'Moral realism' is however a family of theories that take morality to have an objective factual basis, such that morality is not 'up to us' and is not 'under our control'. The contributions in this (...) handbook explore the central ideas and themes constituting moral realism and defend particular views about it. (shrink)

Michela Massimi has written a book broad in scope and ambition but full of wonderful details. It moves from technical philosophical discussions of conditionals to detailed case studies of work in child literacy. From perspectival art to dark matter. From Borges to blown glass – and much else in between. It is impossible not to be impressed. -/- Massimi's book is a detailed elaboration and defence of a position, perspectival realism, she has been developing over several years. Perspectival (...) class='Hi'>realism offers a new twist on realism debates in science. Standard scientific realist views focus on the products of science. They are concerned with questions like whether our current scientific theories are approximately true or our best models accurate. Massimi's perspectival realism, in contrast, focuses on the process of scientific investigation. She is interested in the question of how scientific communities come to produce reliable knowledge. Massimi addresses that question by offering the reader several detailed case studies. The centrepiece of the book is a long and multi-part discussion in Chapter 4 in which she describes the development of models in nuclear physics, climate science, and developmental psychology. The central message of each case study is the same: scientific knowledge emerges through the interaction of diverse scientific communities. For example, crucial to the development of models explaining nuclear stability was prior work done by petrologists, vulcanologists, meteorologists, and others in establishing a consistent pattern of isotopic abundances through a variety of environments. It was this knowledge which in conjunction with other accepted physical constraints, like Pauli's exclusion principle, that led to the development of a series of nuclear models, culminating in Goeppert Mayer and Jensen's Nobel Prize-winning shell model.

In my review of Steven French's The structure of the world. Metaphysics & Representation. OUP, Oxford, 2014 I argue that the author is forced to navigate between the Scilla of Tegmark’s Pitagoreanism (2008) and the Carybdis of “blobobjectivism” (Horgan and Potrč 2008), namely the claim that the whole physical universe is a single concrete structurally complex but partless cosmos (a “blob”).

In his 1904 letter to G.F. Stout, Cook Wilson distinguishes objective and sub- jective conceptions of appearance, and provides a diagnosis for the modern acceptance of the subjective conception in terms of a confused misdescrip- tion of the objective appearances that perceptual experience affords. More- over, Cook Wilson links subjective appearances with idealism, the suggestion being that perceptual appearances must be objective if they are to afford us with something akin to proof of a world without the mind.

Thomasson is a simple realist about the vast majority of entities: she thinks that they exist, and that their existence is to be accepted as a trivial consequence of the truth of various uncontroversial sentences (Thomasson, Ontology Made Easy. Oxford: Oxford University Press, 2015, p. 156). This position is to be taken in contrast to the explanatory realism familiar from dominant post-Quinean metaontology: the view that entities are posited to explain phenomena, and that (very roughly) we should (...) believe in whatever we need in order for our best scientific theories to come out as true. Recent literature further suggests an approach I’ll call ‘fundamentality realism’: the idea that we should understand realism in connection with notions of fundamentality and metaphysical priority. I introduce these notions and the relations between them before describing an objection to Thomasson-style simple realism. I argue that this objection can be overcome by combining simple realism with elements of fundamentality realism, and that such a view can nevertheless be seen to fit with Thomasson's overall metaphysical worldview.

This is certainly true. Simulationists and experimentalists face equally relevant challenges when it comes to establishing that the results of their simulation or experiment are informative about the real world. But it is one thing to point this fact out, and it is another to understand how those challenges are overcome, under differing circumstances, and in varying contexts. It is here that Marcel Boumans’ contribution becomes especially valuable. He presents an example from economics in which a mathematical model performs the (...) role, not of a representational entity, but of a data sensor. Boumans argues, and I concur, that the manner in which such models are assessed is particularly interesting. They cannot be assessed merely by being confronted with facts about the world, since these models are themselves used in generating the relevant data about the phenomena in question. The relevant strategy for assessing these models is calibration. In other words, rather than being held side by side with the relevant bit of the world, the models are held up against other instruments that are antecedently believed to be reliable sources of data.

This article endeavors to identify the strongest versions of the two primary arguments against epistemic scientific realism: the historical argument—generally dubbed “the pessimistic meta-induction”—and the argument from underdetermination. It is shown that, contrary to the literature, both can be understood as historically informed but logically validmodus tollensarguments. After specifying the question relevant to underdetermination and showing why empirical equivalence is unnecessary, two types of competitors to contemporary scientific theories are identified, both of which are informed by science itself. With (...) the content and structure of the two nonrealist arguments clarified, novel relations between them are uncovered, revealing the severity of their collective threat against epistemic realism and its “no-miracles” argument. The final section proposes, however, that the realist’s axiological tenet “science seeks truth” is not blocked. An attempt is made to indicate the promise for a nonepistemic, purely axiological scientific realism—here dubbed “Socratic scientific realism.”. (shrink)

Mental health research and care in the twenty first century faces a series of conceptual and ethical challenges arising from unprecedented advances in the neurosciences, combined with radical cultural and organisational change. The Oxford Textbook of Philosophy of Psychiatry is aimed at all those responding to these challenges, from professionals in health and social care, managers, lawyers and policy makers; service users, informal carers and others in the voluntary sector; through to philosophers, neuroscientists and clinical researchers. Organised around a (...) series of case studies in five key topic areas - concepts of disorder, the philosophical history of psychopathology, philosophy of science, ethics and philosophical value theory, and philosophy of mind - the book provides a detailed introduction to the field and a framework for study and skill development. Each case study is supported by selected readings from both philosophy and mental health, thinking skills exercises, self-test questions, key learning points and detailed guides to further reading. There is an introduction for philosophers to classification and descriptive psychopathology, and for practitioners to philosophical methods (including logic). The philosophical topics covered include philosophical methods (analytic and Continental); phenomenology, hermeneutics and existentialism, logical empiricism and its successors; idealism and realism; reasons and causes; and modern theories of mind and brain, free will and personal identity. Topics from mental health include psychiatry and 'anti-psychiatry'; Jaspers' psychopathology and the new neurosciences; the future of psychiatric classifications; strengths-based approaches, recovery practice, social inclusion and diversity; and key topics in psychopathology, such as delusion, autism, disorders of volition, thought insertion and other experiences in schizophrenia. The Oxford Textbook of Philosophy of Psychiatry aims to secure the skills-base of the discipline by bringing philosophers closer to the realities of practice in mental health, and mental health practitioners closer to the resources of philosophy as a partner to the sciences in responding to the challenges of twenty-first century mental health and social care.
